Shawwal Six Fasts: Health Points to Know Before You Start
The medical short version: the six fasts of Shawwal carry the same health rules as Ramadan fasts. If a condition meant your doctor had concerns about Ramzan, it applies here too, and people with diabetes should check with their doctor before starting. The religious side, such as timing, whether to keep them together and how they relate to missed fasts, is a question for your scholar.
Before you start
- Same body, same rules: a medical condition doesn’t take a break because Ramadan ended.
- Diabetes: doctor first. Break the fast if sugar drops below 70 mg/dL or rises above 300 mg/dL.
- Medicines: the doctor decides timing. Never shift or skip a dose yourself.
- Health advantage: you can often space the fasts out, choose cooler days and rest in between.
- Religious detail: order, timing and intention belong to your scholar.

Eid is over and many people are keen to keep the six Shawwal fasts, even though the body has just come through a month of changed sleep and meals followed by several days of rich Eid food that it may not have fully recovered from. So what does medicine say about starting again? Here, only the health side. For the ruling itself, ask a scholar you trust.
Are Shawwal fasts different from Ramadan fasts for health?
Physically, no. A fast from dawn to sunset puts the same demands on the body whether it’s in Ramadan or Shawwal: no food, no water, lower blood sugar late in the day, and a shifted sleep pattern if you wake for sehri.
Did you know? The Islamic calendar is lunar, so Shawwal moves about 11 days earlier each solar year, which means these fasts slowly travel through every season over a lifetime, sometimes landing in long summer days and sometimes in short winter ones.
Think of it like driving the same road in a different month. The bends and hills haven’t moved. If your car needed care on that road in Ramadan, it needs the same care now.
There are two practical differences worth knowing:
- You may be fasting alone. The rest of the household eats normally, the office has lunch, and nobody keeps you company at sehri, which makes it very tempting to roll over and skip that meal, and that is exactly the habit that turns an ordinary fast into a dizzy, headachy one.
- You may have more choice over days. Many people spread the six fasts out. Medically, that can help, because it allows rest and recovery between them. Whether spacing is fine for your religious purpose is for your scholar to say.
Who should talk to a doctor first?
If your doctor gave you advice or warnings about Ramadan, bring the same questions to them before Shawwal. That includes people with:
- Diabetes, especially on insulin or tablets that can cause low sugar. Our guide to questions to ask your doctor about roza with diabetes works just as well for Shawwal.
- High blood pressure, heart disease or kidney disease.
- Pregnancy or breastfeeding.
- Stomach ulcers, severe acidity or migraines triggered by fasting.
- Older age with frailty, dizziness or several medicines.
- A history of eating disorders.
Yes, yes with changes, or not for now. Only your doctor can decide how your medicines fit around a fast.
Diabetes and Shawwal fasts: the lines that don’t move
Low blood sugar (hypoglycaemia) can come on during any fast, and its early signs, which include shakiness, sweating, a racing heart, sudden hunger, confusion, irritability or blurred vision, are easy to wave away as ordinary fasting tiredness. Don’t. Check.
The house rule is simple. Break the fast straight away if sugar is below 70 mg/dL, or above 300 mg/dL. Break it too if you feel unwell, even before you can check. Take fast-acting sugar for a low, and get help if it doesn’t lift quickly. Religious guidance widely allows breaking a fast for illness; your scholar can confirm what applies to you.
A condition doesn’t pause because Ramadan ended.
A health-first way to keep the six fasts
- Wait until your stomach settles after Eid. Give yourself a few days of normal meals and sleep if Eid food left you unwell.
- Book a quick check with your doctor if you have any condition from the list above.
- Don’t skip sehri. Eat protein and fibre (eggs, dahi, daal, whole-wheat roti) and drink 2 to 3 glasses of water.
- Choose lighter days if possible: not your busiest workday, not a long drive, not the hottest afternoon outdoors.
- Space them out if your body needs it, subject to your scholar’s guidance on timing.
- Break the fast gently: dates and water, then a normal meal rather than a feast.
- Stop and rest if you feel faint, confused or very weak.
Getting your sleep back on track after Ramadan also helps these fasts feel easier; see how to reset sleep, meals and chai after Ramadan.
Myth: if Ramadan went fine, Shawwal fasts are automatically safe
Usually they’re similar, but not always, because your health may have shifted, your medicines may have been changed at a check-up after Ramadan, or the weather may simply be hotter than it was. A good Ramadan is encouraging. Not a guarantee.
You feel faint, confused or very weak, or have chest pain, a racing heartbeat or breathlessness. Also stop for severe headache, repeated vomiting, very dark urine or none for many hours, or, in diabetes, sugar below 70 mg/dL or above 300 mg/dL. Pregnant women should stop and seek care for reduced baby movements, bleeding, pain or dizziness. Never change, skip or move a medicine to fit a fast unless your doctor has told you how; your prescriber sets the timing, and a scholar advises on the religious side. The warning signs in fasting safely: when to stop apply here too.

Shawwal fasting health questions
Can diabetics keep the six fasts of Shawwal?
Some can, with their doctor’s approval and a plan for medicines and sugar checks. Break the fast if sugar goes below 70 mg/dL or above 300 mg/dL, or if you feel unwell.
Are Shawwal fasts harder than Ramadan fasts?
Same demands. Many find them harder alone, though, so keeping sehri and choosing calmer days helps.
Should the six fasts be kept together or separately?
That’s a religious question for your scholar. Medically, spacing them can give the body rest, which suits some people with health conditions.
Can someone with high blood pressure fast in Shawwal?
Many people with well-controlled BP can, but ask your doctor first, especially about medicine timing and how much salt goes into iftar, and don’t move any doses around on your own to make the day easier.
Is it safe to fast in Shawwal while breastfeeding?
It depends on the baby’s age, how feeding is going and your own health, so talk to your doctor first, drink well through the night, and stop the fast if you feel faint or notice the baby is having fewer wet nappies than usual.
What should be eaten at sehri for a Shawwal fast?
Protein and fibre that last, such as eggs, dahi, daal, whole-wheat roti or oats, with 2 to 3 glasses of water, while salty pickles, crisp parathas soaked in oil and very sweet foods tend to make the thirsty afternoon hours much harder.
How soon after Eid can the six fasts start?
Your scholar can advise on the religious timing, while from a health point of view it’s sensible to wait until your stomach has settled after the Eid food and your sleep is back to something like normal.
What are the signs of low sugar during a fast?
Shaking, sweating, a pounding heart, sudden hunger, confusion, irritability and blurred vision.
Can someone with kidney disease keep the six fasts?
Only if their kidney doctor agrees. Long hours without water can strain weak kidneys, and many people with kidney disease are advised not to fast.
Can older parents keep Shawwal fasts?
Healthy older adults often manage. Frailty, dizziness or several medicines mean a doctor’s check first.
Who decides about fidya or skipping these fasts for health reasons?
Your scholar decides the religious side, and your doctor decides whether fasting is medically safe for you, so the best step is to bring your doctor’s advice with you when you ask the scholar, giving them the full picture before they answer.
